Simulation of conduction cooling of a 650MHz 5-cell cavity

Abstract

The research note presents results of coupled RF and thermal simulation of a cryocooler conduction cooled 650 MHz SRF cavity made of bulk niobium and coated with Nb3Sn on the RF surface. The cavity is part of a particle accelerator design capable of producing 10 MeV, 1000 kW electron beam for application in wastewater treatment. More details of the accelerator design are presented in R.C. Dhuley et al. (2022) Phys. Rev. Accel. Beams 25, 041601.
